Vorrichtung und Verfahren zur Steuerung eines ausblasbaren Gassacks

摘要

An air bag pressure control system for use in a vehicle (10) is provided. The system comprises a housing (16), an inflatable cushion (20), and a dual stage inflator (18). The inflator generates a quantity of inflation gas to deploy the inflatable cushion from the housing. A vent opening (56) is formed in the housing to selectively direct a portion of the inflation gas towards or away from the inflatable cushion. A sensing and diagnostic module (22) detects an activation event level. A control algorithm (112) tailors an inflation level of the inflatable cushion during deployment according to the activation event level.
